1. Double-click My Computer.
2. On the View menu, click Options.
3. Click the File Types tab.
4. In the Registered File Types box, click File Folder, and then click Edit.
5. In the Actions box, click Find, and then click Set Default.
6. Click Close, and then click Close.
After you follow these steps, double-clicking a folder causes the Find tool to open.


Now I want to know is it possible to roll back the abve changes because due to the above change double click property of the folder is changed to find always. I want the double click property to show the content of the folder.
